Possible Moment of Progress

Whoa guys, something crazy just happened to me. I just effortlessly thought and said a Spanish sentence that I would have never said three weeks ago. I was trying to decide whether I wanted to eat lunch or wait from my host brother and sister to get home from school and I asked, "¿A qué hora regresan los niños?" Before I was in Ecuador I didn't know the verb regresar and, more importantly, I would not have put the words in that order. I think this means that I may actually be starting to learn new Spanish and unconsciously learning the grammatical patterns of the Spanish I am hearing. Hopefully this learning Spanish business will continue, because I would really like to know what the hell is going on during school.
